Supervisors who will determine when an employee is subject to drug testing based on reasonable suspicion must receive at least 60 minutes of initial training, including specific training on:
- The effects and consequences of drug use on individual health, safety, and work environment
- The manifestations and behavioral cues that may indicate drug use and abuse
- Specific, contemporaneous physical, behavioral, and performance indicators of probable drug use
Employers must also provide recurrent supervisor drug training. The FAA recommends as a best practice that employers conduct recurrent training on a 12-18 month schedule.
Supervisors who make reasonable suspicion determinations for alcohol testing must receive at least 60 minutes of training on the physical, behavioral, speech, and performance indicators of probable alcohol misuse.
Although DOT regulations do not require recurrent alcohol training, the FAA recommends as a best practice to include a review of the alcohol testing requirements while conducting recurrent drug training.
